“By media market, the race is a dead heat in the Seattle DMA: McKenna gets 36% of the vote and Inslee 35%. McKenna leads by double digits in the Eastern Washington markets of Yakima and Spokane, but his lead is not outside the margin of error in the Portland DMA, where more than half of voters are currently undecided. At this stage of the campaign, this race appears very fluid with almost one-in-three voters not opting for either candidate. However, among those who have decided, McKenna is hitting the right targets and doing well with the audiences he must have to win statewide,” Moore said in analysis of their data. Moore often does work for Republican clients.

The survey of 500 voters was taken Sept. 10-11. The margin of error was 4 percent.

Other polls from SurveyUSA/KING5 and Strategies 360 also had McKenna ahead.
